I understand why it is desirable! But why is Bitcoin better for this than, say, an index fund?
Even in the case of an index fund, you are ultimately buying shares of businesses which decreases the cost of financing for those businesses and helps them to grow. It's not as impactful as an angel investment in a startup, but it still means that your outcome is linked to successful economic activity that you helped to finance. In the case of Bitcoin, no such activity takes place, so where is the reward coming from?
